UEFA confirmed earlier this month that squad sizes have been increased from 23 to 26 players for this year's eagerly-anticipated continental tournament, and all squads must include at least three goalkeepers.
However, most nations are taking the approach of initially selecting a group of players that exceeds the squad limits with friendlies planned beforehand.
Here, Sports Mole takes a look at the Scotland players that have been selected, and which players have missed out on being in contention for the tournament in Germany, which begins next month.
Which Scottish stars have been selected?
There have been a number of Scotland stars that have experienced injury issues this season, including the likes of Liverpool defender Andy Robertson and Manchester United midfielder Scott McTominay.
However, the pair are the headline names in Clarke's squad, with Aston Villa's John McGinn and Celtic's Callum McGregor also selected as midfield options.
Stuart Armstrong also features on the list, despite the Southampton midfielder missing the last month of action through injury, with Brighton & Hove Albion's Billy Gilmour also in line to challenge for a starting spot.
Kieran Tierney has endured a mixed campaign on loan at Real Sociedad but takes on a senior role in this squad, as will Lyndon Dykes who is one of five designated attackers.
Norwich City's Angus Gunn is one of four goalkeepers selected by Clarke, but that will have to be reduced to three by June 7.
Which Scottish stars will miss Euro 2024?
Scotland have already been dealt a harsh hand with regards to injuries with Nathan Patterson, Aaron Hickey and Lewis Ferguson already being ruled out.
That has played its part in Ross McCrorie and Ben Doak both being handed call-ups to the squad, despite failing to make an appearance for the Tartan Army thus far. Ryan Jack and James Forrest are also named.
There are very few other surprises. Jacob Brown and Kevin Nisbet - of Luton Town and Millwall respectively - may have hoped to sneak into the attacking options, but they only have one international goal between them in 19 caps.
What are Scotland's pre-tournament preparations?
Scotland will first square off against international minnows Gibraltar in a friendly on June 3, that fixture taking place in Almancil in Portugal.
Four days later, on the same day that the official squad must be finalised, Scotland play host to Finland.
Clarke's side then have a week to prepare for their first game, squaring off against tournament hosts Germany in the opening fixture of Euro 2024.
